Angry Birds used in Physics exam

It's pretty common for those stuffy examiner types to try and be down with the kids. Remember when your maths exam included a reference to compact discs in an equation?

But, in our time outside of education, it seems as if they've been getting even more edgy.

Take a look at this physics exam that uses Angry Birds to illustrate a question. It's a genius idea, although we'd also like to see a biological explanation for why pigs stay so damn stationary when birds are attacking them in force.
